Hefei Bolin Advanced Materials Co., Ltd. was founded up in 1997, who is engaged in oilless self-lubricating wrapped bushing and bearing and structure powder metallurgy parts.

We are producing full line of self-lubricating, marginally lubricated and fully lubricating plain bearings. . Our products are available in a variety of forms such as cylindrical wrapped bushes, flanged bushes, thrust washers, etc.

As the picture shows, the material is three layers, of which the base plate is cold-rolled steel, the middle layer is porous sintered bronze powder, and surface layer is improved PTFE.  By the special craft and unique structure, the self-lubricating bearing gains excellent mechanical properties, good anti-friction and wear resistant.

Feature:

1. Thickness of improved PTFE:  0.010.05mm

2. Thickness of Spherical Bronze : 0.25~0.30mm

3. Thickness of Steel Back: 0.7~2.2mm

4. Thickness of electroplate Cu Sn 0.003~0.008mm

5. Excellence wear-resistance, low friction coefficient

6. Free maintenance or less maintenance, suitable to rough lubrication.

7. Low noise and environmental friendly

We offer customized oilless bushing and bearing to meet your specific requirements.

Warmly welcome to visit our new factory!
